SW'ITCH.

SPECIFICATION forming part of Letters Patent No. 320,019, dated June 16, 1885.

Application filed March 7, 1885. (N0 model.)

To all whom it may concern.-

Be it known that I, ERASTUS O. TITUs, a citizen of the United States, residing at Gatskill, in the county of Greene and State of New Yorl ,have invented a new and useful Improve ment in Switches, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to an improvement in switches to be used in connection with a telephone system; and it consists in the peculiar arrangement that will be more fully set forth hereinafter.

In the accompanying drawings, Figures 1 and 2 are reverse plan views of one of my switches. Fig. 3 is a diagram illustrating my switch in connection with a telephone systern.

A represents a switch-board, to one side of which are secured eight binding-posts, 1 2 3 4 5 6 7 8. An insulating-strip, B, is secured near the opposite side of the board, through which pass four contact-points, I II III IV.

0 represents a series of six levers, which are pivoted to the switch-board at the points a b c d e f, and which are connected together by an insulatingstrip, D, near their free ends. A knob, E, is attached to this connectingstrip, and stops F G are secured to the switch board, one on each end thereof, which stops are located at a sufficient distance from the row of contact-points to allow two of the levers to clear said row of points and the third lever from either end to come in contact with the outside point when the levers are moved to either side. Wires connect the contactpoints to the bindingposts as follows: I to 1, II to 2, III to 7, IV to 8. The points a and e are connected to the post 5, b and f to the post 6, c to post 3, and d to post 4, as shown at Fig. 2.

The operation of the switch is as follows: In

the diagram, Fig. 3, Y represents an office that is connected to two officcs, X and Z. The office Y is provided with a telephone, a call-bell, and with one of my switches, as shown. \Vhen the switch is turned to the left, as illustrated in solid lines, the office X is in circuit with the telephone in office Y, while the office Z is in circuit with the calLbell in office Y, which enables Z to call Y at any time. When the switch is turned to the right, as illustrated in dotted lines, the telephone in office Y is in circuit with office Z, while the call-bell in office Y is in circuit with office X, which enables X to call Y at any time. Heretofore in a telephonic system of this character it would be necessary for the office Y to have two telephones, one in circuit with each of the offices X and Z; but by the use of my switch and a call-bell but one telephone will be necessary, as will be very readily understood, and thus the rent of one telephone will be entirely saved.

Having thus described my invention, I claim-- The switch having the binding-posts 1 2 3 4 5 6 7 8 the contact points I II III IV and the switch-levers secured to points a b c d e f, which levers are connected together and adapted to be moved simultaneously, the contact-points I II being connected to the posts 1 2, contact-points III IV being connected to the posts 7 8, points a 6 being connected to post 5, points b f being connected to post 6, point 0 being connected to post 3, and point at being connected to post 4, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signatnrein presence of two witnesses.
